- Content-based classification, search and retrieval
Muscle Fish's CBR (content-based
retrieval) technology allows you to search for audio files on the
basis of how they sound. It can also be used to classify
sound files or live sound inputs. A variety of demos are available
on our Audio Demos page.
The Video Cataloger product by Virage,
Inc uses Muscle Fish's technology for speech/music discrimination
and other audio classification tasks.
The Muscle Fish audio
retrieval technology brings powerful new capabilities to a wide
array of applications, ranging from sound databases to
audio editors, and even extending to
audio-aware process control or monitoring systems. For more
technical details and specific application ideas, see a
recent article here.
- DSP algorithms
Our time-scaling and pitch-shifting
technology lets you change a sound file's length and pitch independently.
For example, you can make a sound play twice as slowly without
making it sound lower. Or you can make it higher in
pitch without making it play faster. The signal-processing
algorithms used in this demo are available for licensing.
We have a variety of other audio signal processing
algorithms available for licensing, including reverberation, flanging,
peak limiting and various filters.
